Kenmore Dryer Error Code E2

E2 on a Kenmore dryer means the control board has detected a shorted circuit in the thermistor, which is the component that monitors temperature inside the dryer. When the thermistor circuit shorts, its resistance drops abnormally low and the control board cannot get a valid temperature reading. The dryer stops operation and displays E2 to alert you to this fault. A thermistor test (Test #3C) is the starting point for diagnosing the root cause.

You should not continue operating the dryer while E2 is active. The thermistor is responsible for monitoring heat levels inside the drum, and with a shorted sensor the dryer cannot regulate temperature properly. Running the dryer in this condition risks overheating, which can damage components or create a fire hazard. The dryer should remain off until the fault is diagnosed and the sensor circuit is restored to proper function.

Repair costs depend on which component has failed. A replacement thermistor is generally an inexpensive part, with DIY costs typically in the range of $15 to $40 for the part alone. If the repair requires professional service, labor charges will add to that figure, bringing the total to roughly $100 to $200 depending on your area. A control board replacement, if it turns out to be the root cause, is significantly more expensive and can range from $150 to $350 or more including labor.

A knowledgeable DIYer can diagnose and repair an E2 error by performing the thermistor resistance test and inspecting the wiring harness for damage. If the thermistor itself has failed, it is a relatively straightforward part replacement. However, if the short is located in a damaged harness or a connector that requires careful disassembly, some comfort with appliance wiring is needed before attempting the repair.

Resetting the dryer by unplugging it or cycling the power may temporarily clear the E2 display, but the error will return quickly if the underlying short in the thermistor circuit has not been corrected. A reset alone does not repair a failed thermistor, damaged wiring, or a faulty connector. Clearing the code without addressing the cause will result in the dryer faulting out again, often immediately upon starting a cycle.
